Note 11 — Chapter XIII

Guaraná is the fruit of a low wide-spreading tree. It is about the size of a common walnut, and contains, within, five or six small seeds. These seeds are toasted, ground, mixed with a little water, pressed into moulds, and dried in an oven. Two spoonfuls, grated into a tumbler of water, is thought to make a very refreshing drink. It is said to be a stimulant to the nerves, and, like strong tea or coffee, to take away sleep. It grows principally on the banks of the upper Tapajos, and is much used by the inhabitants of Matto Grosso.
